Ten years after one of the most deadly tsunamis ever known, scientists are making a shocking discovery. Experts used to believe that the biggest killer waves were only generated in a handful of regions, but mounting evidence now suggests that more of the world’s coasts, from the Mediterranean to Australia, could be in grave danger.

Calm was the last thing that Could We Survive a Mega-Tsunami? (BBC Two) was trying to create. Instead the objective of this imagined staging of a super wave hitting Europe and America appeared to be the creation of enough fear to have paranoid survivalists fleeing up the nearest mountain to barricade themselves in. What else was this Hollywood-style, CGI-heavy bad dream with hysterical voice-over and tribal wailing trying to achieve? Understanding for the real survivors of the real tsunamis that really killed 200,000 people and devastated the Indian Ocean region in 2004? Or the even more recently traumatised victims of this natural horror show in Japan? I hadn’t detected a world sympathy deficit following these events, and use of real footage of the carnage from those disasters mixed up with fantasy sequences seemed gratuitous.

Catastrophe is sadly never far from the news headlines, with this year's tsunami in Japan and the Chilean earthquake of 2010 continuing to loom large in the memories of millions. In the UK premiere of Doomsday Earth join experts who examine the likelihood of the planet being struck by both a mega-tsunami and a mega-quake. Their findings are not good news. It seems a giant fault line beneath the sea is readying itself for a violent explosion of activity, and the race is on to calculate when rather than if, this 'megathrust' will do its worst. They're focus is also on the terrifying trend that has seen the Earth struck by a series of devastating natural disasters. And they predict that the worst could still be yet to come…where do you think Mother Nature will strike next?

Scattered across the world’s oceans are a handful of rare geological time-bombs. Once unleashed they create an extraordinary phenomenon, a gigantic tidal wave, far bigger than any normal tsunami, able to cross oceans and ravage countries on the other side of the world. Only recently have scientists realised the next episode is likely to begin at the Canary Islands, off North Africa, where a wall of water will one day be created which will race across the entire Atlantic ocean at the speed of a jet airliner to devastate the east coast of the United States. America will have been struck by a mega-tsunami.
